2021 Mercedes-Benz G-Class price and specs

The wild Mercedes-AMG G63 is joined this year by the more affordable, turbo-diesel six-cylinder Mercedes-Benz G400d.


It’s the chariot of choice for everyone from rappers to Kardashians to even the Queen of Jordan. Now, the Mercedes-Benz G-Class has gotten a little more accessible.

The turbo-diesel 2021 Mercedes-Benz G400d joins the Mercedes-AMG G63 in the redesigned, second-generation G-Class range.

Arriving in July 2021, the G400d will be priced at $233,900 before on-road costs, or $56,000 less than its petrol-powered AMG counterpart.

Under the bonnet is Mercedes-Benz’s OM 656 engine, a 3.0-litre turbo-diesel inline-six producing 243kW of power and 700Nm of torque.

Fuel economy is rated at 9.5L/100km on the ADR combined cycle, while 0-100km/h takes 6.4 seconds.

This engine is also used in the Mercedes-Benz GLS400d, among other vehicles from the three-pointed star brand.

The body-on-frame off-roader has three differential locks for its all-wheel drive system and adaptive suspension, the latter of which also helps with its on-road comfort.

The G400d has a stainless steel exterior package, which includes the running boards and spare wheel cover.

Standard equipment also includes a 15-speaker Burmester surround-sound system, tri-zone climate control, and a surround-view camera.
